- Soumenlinna from one end to another would be at least a mile long and given detours, one need to travel at least 3-4 miles to cover the basics. Be ready for these long walks.
- There are beautifully placed restaurants and cafes within the fort walls that tempt you to just settle after a long walk. Do that.
- The periphery throws great views of the sea and parts of fort island. Make sure you walk along the edges to cover that.
Soumenlinaa & Vallisaari are two islands south of Helsinki in the Baltic Sea. It takes €4 and half hour to reach the islands - cheap for the rustic life one witnesses here. It was the same day we reached Helsinki that we ventured for these islands and loved what we saw. Clearly the brightest gem of tourist spots in Helsinki, that were a perfect start to our visit to Scandinavia.
